On Building Great Paragraphs

2. Coherence
Coherence refers to a certain characteristic or aspect of writing. Literally, the word means "to stick together." Coherence in writing means that all the ideas in a paragraph flow smoothly from one sentence to the next sentence. With coherence, the reader has an easy time understanding the ideas that you wish to express.
Connectors are words that we use to add coherence to our writing. They tie ideas together.

3. Some Examples of Connectors
* For example, * For instance, * One example of (this) is * First, Second, Third, etc.
* On the one hand, * On the other hand, * However, * ..., but... * Also
Think about the other transition words we learned about last week. What else can you come up with?

4. Example #1 – Determine if the following paragraph is coherent or not.
My hometown is famous for several amazing natural features. First, it is noted for the Wheaton River, which is very wide and beautiful. On either side of this river, which is 175 feet wide, are many willow trees which have long branches that can move gracefully in the wind. In autumn the leaves of these trees fall and cover the riverbanks like golden snow. Second, on the other side of the town is Wheaton Hill, which is unusual because it is very steep.  Even though it is steep, climbing this hill is not dangerous, because there are some firm rocks along the sides that can be used as stairs.  There are no trees around this hill, so it stands clearly against the sky and can be seen from many miles away.The third amazing feature is the Big Old Tree. This tree stands two hundred feet tall and is probably about six hundred years old. These three landmarks are truly amazing and make my hometown a famous place.

5. Identifying Connectors
Remember the words in italics font? Do you see how they help guide the reader? For example, consider the words, First, Second, and The third amazing feature. We can call these words major connectors. Major connectors help organize the main parts of your paragraph. This paragraph has three main parts:
(1) a part about the Wheaton River,
(2) a part about Wheaton Hill, and
(3) a part about the Big Old Tree.
Another way of saying this is that this paragraph has three main points which are indicated by the major connectors. Using such major connectors is an important way of providing coherence in a paragraph.

6. Identifying Connectors, Continued
What about the other words in italics, such as those appearing in the phrases "these trees" and "this hill"? We can call these minor connectors. Minor connectors provide coherence to a paragraph by connecting sentences within each of the main parts of your paragraph. That is, when you write about your main points, you can use minor connectors to link your details to each main point.

7. Unity
Unity is a very important characteristic of good paragraph writing. Paragraph unity means that one paragraph is about ONLY ONE main topic. That is, all the sentences -- the topic, supporting sentences, the detail sentences, and (sometimes) the concluding sentence -- are all telling the reader about ONE main topic. If your paragraph contains a sentence or some sentences that are NOT related to the main topic, then we say that the paragraph "lacks unity," or that the sentence is "off-topic."

8. Example #2 – Determine if the following paragraph is unified or not.
 Each of the Russian manned space exploration projects had specific major goals. For example, the Vostok project was designed to test whether or not human beings could survive and function in outer space. For another example, the Voshkhod project was intended to find out whether people could work in the weightless environment of space. One Voshkhod cosmonaut experimented with weightlessness by taking a "spacewalk." That is, he floated in a spacesuit outside his Voshkhod spacecraft, connected to it by a tether. The cosmonaut to do this was Alexei Leonov. Several weeks later, Leonov's spacewalk was followed by that of U.S. astronaut Ed White. Finally, the Soyuz project, with three cosmonauts, had goals of testing spacecraft and spaceflight skills so that people could fly long missions in Earth orbit.

9. Identifying Unity
This paragraph is generally good, but the sentence, “Several weeks later, Leonov's spacewalk was followed by that of U.S. astronaut Ed White,” does not have anything to do with the major goals of the various Russian space projects. That is, it is an "off- topic" sentence, so we can say that the paragraph somewhat lacks unity. In order to improve the paragraph, we should omit this sentence, even though it is historically accurate.

10. Try Your Own
Write one paragraph about texting while driving. Should this be illegal? Why or why not?
First, take a clear position on the subject.
Come up with three supporting details that support your argument.
Use connector words to create cohesion in your paragraph.
When you are finished, check for unity:
Are you following the ONE topic you chose?
Do your sentences flow together?
